` MACHINE FR FINISHING BARRELS.

SPECIFICATION forming` part of Letters Patent No. 283,477, dated August21, 1883. Application'led March 21,1882, (No model.)

` To all whom, it may concern:

` Finishing Barrels; and `I do hereby declare that the following is afull, clear, and exact description thereof.

My invention relates to devices for iinishing barrels, andvwill be fullydescribed hereinafter.

In the drawings, Figure l'is a side viewv of my invention Fig. 2is anend view. Fig'. 3

is a transverse section through the center of the same. Figi a isasection through line .fc fr, Fig. l, and Figs. 5 and 6 are details.

A is the frame ofmy machine, which should consist of solid timberssecurely bolted together, and B B are the bedpieces, that carry strips BB', preferably of metal. 'The strips B B serve as ways for the feet ofthe pillowblocks C C to. travel upon. These pillowblocks conta-inthebearings for thehollow shaft C', that carry the chuck-disks D, and thefeet b of each pillow-block have bearings for a rock-shaft composed ofsections c c', the end of one section, c, of which telescopes into theother section, c', Both of my chuck-disks are alike, and therefore Irefer in my description to only one of them. Y

D is the disk, which I provide with a hub, d, that is keyed on shaft C.The disk has a rim, e, that extends back in the direction that the hubdoes, and between this rim and the hub I place a ring, Il, that hastangentialslots e', while I provide the disk D with radial slots d',that' crossthe slots e', and I insert the shank of a finger, E', througheach of the slots e and d and vsecure it by a nut on its threadedend. Onone end of this linger is a shank squared to fitin the slot d', and thenthe shank terminates in a screw-bolt that, passing through the slot e inthe ring Il, receives a nut, f. Now, as the only play that the finger Eis capable of is in the direction of the length cf the slot d', when thering E is turned in one direction the slots e will have a tendency towedge the Shanks of these ngers out tothe extreme line of the slots d,and when: turned back it will have an opposite tendency, and of courseall of these fingers will b'e moved together. The

ends of the fingers that are designed to take the end of the barrel havebeveled flanges that rest on the outside of the end of the barrel andclasp it in position as the two chucks are drawn together. By chucks7Imean the Ydevice that consists ofthe disk, ring, and n gers on each ofthe revolving hollow shafts C. To permit the placing and removing of thebarrels, I make the pillow-blocks G adjustable with relation to eachother and connect them by rods F F to the ends of a cross-bar on ashaft, F', that passes through the bed-pieces B, and I provide Jtheshaft with a ratchet and pawl for holding it in any position that it maybe set in-that is, after the barrel has been placed, the shaft, whenturned, will draw the chucks tightly against the ends of the barrel andhold it there while it is being iinished.

Inside of the shaft C', I place a stationary hollow sleeve, G, which Iclamp in place by a set-screw, g, and I Square the inner end of thissleeve and groove it to receive the tongued sides of a blockbrcross-head, H, the upper side of which is dovetailed to take the slideof a tool-holder, I. The latter is connected by an adjustable arm, I,with the crank 7c of a solid shaft, K, that, passing through the sleeveG, extends out beyond its end to take another crank-arm, k', that islinked to a section of rock-shaft o c, and as an arm is linked to eachsection, one movement of the arm will turn the shaft Kin each chuck andadvance or withdraw the tool-holder. rlhe shaft of each of the chucks isprovided with a pulley, R, and beneath them I hang a shaft, S, havingpulleys S', that are belted to the pulleys R on the ehuckshafts, and inthe center of shaft S, I provide pulleys rI TQ and between them aclutch, T2. Belts N N', leading from pulleys on a counter-shaft, passover rollers s in the frame, np over the pulleys T T and back over s',and back down to the pulleys on the counter-shaft again, and thus thepower to revolve the shaft S is taken in an almost horizontal direction,which admits of the shaft S being raised and lowered to tighten orloosen the belts when it is desired to start or stop the chucks. Theraising and lowering are done by cams P on rock-shafts Pf, that passthrough the end pieces of the frame, and the arms of these shafts areconnected by rods p p with a toggle-lever, Q, by which they areoperated. The belt oi pulley I,l I design driving by a pulley on thesame shaft that carries the pulley that drives IOO ` shaft S that I canwith pulleyvT.

pulley T, but of twice the diameter, so that with pulley T, I can givetwice the speed to Pulley T turns loosely on shaft S, but has a tooth,t, for engagement with a similar tooth on the clutch, so that when theVgreatest speed is desired the clutch has but to be shifted over onto it.The pulley T is adapted to revolve freely on its shaft only in onedirection, so that when the shaft is being revolved at its most rapidrate it will not be retarded by the slow revolution of said pulley; butI provide it with a springclutch, fw, that, when the pulley T is out ofgear, will take into a hub on the shaft and revolve it only half as fastas the pulley T would.

To provide a support for the smoothing-tool for the outside of thebarrel, I secure uprights V to the bed-piece and extend a slightlycurvedrod, V', from one to the other. This rod carries one end of thesmoothing-tool, which, after it has done its work, may be carried to oneside and swung up out of the way, to give place to a sand-paper pad, IV,that is swiveled to a rod, W', above it.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination of the disk D, Vhaving radial slots d', and providedwith hub cl and rim e, each extending back in the sam'e direction, withthe ring E, located between said hub and rim, and having tangentialslots e, and the fingers FK, having hooked ends and shanks squared to twithin the slots d@ and then terminating in screw-bolts to pass throughslots e, and secured in position by mits f, all substantially as setforth.

2. The combination ofthe disk D and rings E, slotted as described, andconnected together by fingers E, with the shafts O, ways B,pillow-blocks C, rods F F, connected to the ends 4o of a cross-bar onshaft F', and ratchet and pawl, all substantially as set forth.

3. The revolving hollow chuck-shaft and a vstationary shaft passingthrough it, and carrying across-head on which the tool-holder 45 slides,in combination with a rod passing through the last-mentioned shaft, acrank on said rod, and a pitman connecting to the toolholder foroperating the tool-holder, as set forth. 5o

4. The combination, with the cross-heads, carrying each a slidingtool-holder, of a rod for each chuck, cranked to its tool-holder at oneend, and links connecting said rods to a `telescoping rock-shaft,whereby the tools may 5 5 VALLAGE L. FIELD.
